DPPH^• and ABTS^•+ scavenging activities of leaf extracts from the L. shawii.

Radical scavenging activity		Solvent extract				Positive control
Radical scavenging activity		Aqueous	Methanol	Ethanol	Ethyl acetate	GSH	Trolox
DPPH^•	IC₅₀ (mgmL⁻¹)	0.7	0.06	0.1	0.07	0.005	ND
DPPH^•	1/IC₅₀	1.4	16.7	10.0	14.3	200	ND
ABTS^•+	IC₅₀ (mgmL⁻¹)	0.15	0.007	0.075	0.015	ND	0.0025
ABTS^•+	1/IC₅₀	6.6	142.8	13.3	66.7	ND	400

ND: Not Detected; IC: Inhibitory Concentration; IC₅₀, the concentration required to inhibit 50% of radical.
